Some of the experimental problems faced when attempting dislocation tomography are discussed. A method of 3D reconstruction of straight line segments with much lower experimental requirements than tomography is proposed. This method is applied to dislocation structures found in two iron aluminium alloys (28 and 40 at.% Al). Resulting information on statistical distribution of dislocation segment lengths and orientations is presented.
